Hey no worries! I am hoping the Encyclopedia confirms stuff, though that may end up taking a long time lol.
Righty, I was assuming from Shadows of Reach's wording that because it's in "the line, which featured the MA37", which is MA5, it's of the same series. Thanks for taking the time to explain this decision, it's appreciated.
Hey there! Just thought I'd say thanks for the help!
The MA40 currently isnt confirmed to be in the MA5 series, so we currently list it as part of the overall MA series instead!
Hope this is clear to why I reverted the two edits!
